Patented Dec. 21, 1937 PATENT OFFICE CUSHION FOOT FOR CHAIRS George D. Schermerhorn, Reading, Mich.

Application May 1, 1935, Serial No..19,263

2 Claims.

' My invention relates to an improved cushion foot for the leg of a chair or other article of fur- An-ob'ject is to provide an improved cushion foot which may be formed of rubber or other suitable material and which is so constructed that it mayice-quickly and securely connected with the leg of a chair or other piece of furniture and is also so constructed that it is adapted to inherently automatically securely engage with the leg to which it is attached against accidental release or detachment therefrom.

My improved foot element and the leg to which it is attached are provided with interengaging or interfitting parts so constructed and arranged that upon positioning of the foot element upon the leg element these parts interconnect with each other to hold the foot firmly in place upon the leg. I

An improved characteristic of my invention resides in the provision of a cushion foot structure formed as an integral piece and hollowed out to be received over the end of the leg adapted to receive the same and which foot and leg are provided with cooperating abutting parts adapted to slide over each other into locking interengagement to hold the foot to the leg.

In the attachment of the foot element to the leg element there is a yielding on the part of one element which permits the movement of their interengaging parts into locking connection. Preferably, the foot element is formed of yieldable material and is provided interiorly with a wedgelike portion which yields to slide over the cooperating part on the leg upon the insertion of the foot over the end of the leg and which wedge portion interengages with such cooperating part on the leg to secure the foot thereto.

Other objects, advantages, and meritorious features of my invention will more fully appear from the following description, appended claims, and accompanying drawing, wherein:

Figure 1 is a side elevation of a chair the legs of which are provided with my improved foot elements,

Fig. 2 is an enlarged fragmentary sectional view through the leg of a chair provided with my improved foot,

' Fig. 3 is a vertical sectional view taken on line 3-3 of Fig. 2,

Fig. 4 is a fragmentary sectional view taken on line 4-4 of Fig. 2,

Fig. 5 is a vertical sectional view through my improved foot,

Fig. 6 is an elevation of a fragment of a tubular chair leg partly broken away and provided with an improved foot embodying my invention,

Fig.- 7 is a horizontal sectional view takenon line l----! or Fig. 6, and r Fig. 8 is an elevation of a fragment of a tubular leg provided with a modified form of my improved foot.

Whilemyimproved foot is illustrated invconnection with the legs of a folding chair it is obvious that it is adaptable for use with supporting legs of any article of furniture upon which it may be desired to employ the same. Furthermore, while it is here illustrated as being employed in connection with metal legs, it is clearly usable in connection with legs formed of other materials.

My improved foot is adapted to be quickly attached to the leg of the chair and to securely hold its place thereon against accidental detachment. Cushion foot structures have been widely used, but one disadvantage that has attended their use is the provision of suitable means for securing them in place and which will permit the ready replacement of said foot structures.

In the several figures of' the drawing my imwhich the foot is adapted to be received is shown d as being in channel form in cross section. This leg is indicated as H) and it is provided with a channel I2 closed at the lower end by an end wall M. The foot structure is indicated generally as Hi. It is shaped and hollowed out to be received over the end of the leg as illustrated in the several figures. This foot structure is provided interiorly with a -part or lug l8 which projects inwardly from one side wall and is, as shown in Fig. 3, of a wedge shaped formation sloping graduallyinwardly from the top of the side wall toward the bottom thereof and terminating at 18 spaced from the bottom of the foot.

' Figs. 3, l, and 5 show this construction more clearly. The side of the foot is deformable and yieldable and the foot structure may be inserted over the end of the leg, the side portion yielding to permit of such insertion and the wedge part of lug l8 yielding outwardly to slide over the end M of the leg to a positionas shown in Fig. 3 where it extends into abutting relationship superimposing the end wall [4 of the leg and disposed within the channel thereof. In this position the foot is locked securely upon the leg against accidental detachment. Considerable effort is required to move the foot.

In Figs. 6 and 7 I have shown a modified form of construction wherein a tubular leg 20 is provided. A portion of the side wall of the leg is bent inwardly so as to expose a portion of the top of the end wall 24 of the leg. The cushion foot structure is of a character similar to that described in conjunction with the first five figures of the drawing except that naturally it is of a shape to be received over the end of the leg. This cushion foot structure is indicated generally as 26 and it is provided with an internal abutment 28 which is adapted to cooperate with the projecting ledge or flange of the end wall 24 of the leg to hold the foot thereon as illustrated particularly in Fig. 6.

In Fig. 8 a second modified form is shown. In-

this construction the leg is also tubular. It is provided with an end wall 30 which has a skirt 32 that encircles the end of the leg. The foot 34 is provided with an interior wedge shaped ledge or flange 3B which is adapted to form abutting engagement with the edge of the skirt 32 as shown in Fig. 8 to hold the foot on the leg.

In these several figures it will be noted that the constructions illustrated are of such a character that the foot structures grippingly engage the legs of the chair and are yieldable to permit insertion thereover and are provided with interiorly formed abutments adapted to slide over cooperating abutments formed on the legs to which the foot structures are attached and to cooperate with these abutments on the legs to hold the foot structures thereon.

What I claim is:

1. In combination with a leg channel shaped in cross section having an end wall closing said channel, a foot structure hollowed out to be received over the end of the leg and provided with an interior abutment spaced above the bottom of the foot and projecting over the top of the end wall of the leg into the channel thereof when the end wall of the leg is seated against the bottom of the foot.

2. In combination with a leg channel shaped in cross section having an end wall closing said channel, a foot structure hollowed out to be received over the end of the leg and provided with a wedge shaped lug projecting inwardly from a portion of its side wall and receivable within the channelrof the leg above the end wall thereof when said end wall seats against the bottom of the foot.
